Nothing special. After laminating add a coat of epoxy and microballoons then sand that back with an orbital sander till smooth. Then wet hand sand at 180 grit. Then paint with epoxy undercoat 1 or 2 layers and wet sand by hand to 400 grit. Then paint one or 2 coats epoxy top coat with roller, laying off with a high quality brush. surface preparation is the key. But a 5' board is so small its a pretty simple job. Each coat is maybe 50-100mls total and most gets sanded off so adds very little weight and much more durable than a wet sanded undercoat finish that seems to be so trendy.
